  • Page 6: Design Features

    Design Features Compressor Structure All compressors are fitted with Stream valve plates which cannot be dismantled. To maintain the high capacity of these compressors the correct valve-plate-to-body gasket must always be selected in case of exchange. Each cylinder head has 2 plugged 1/8” - 27NPTF tapped holes for connecting high-pressure switches.

    Oil Circulation Oil returns with the suction gases through a suction strainer and separates in the motor chamber reaching the crankcase by way of oil return relief valve in the partition between motor housing and crankcase. This relief valve closes on compressor start-up due to the pressure difference arising between motor side and crankcase, thus, slowing down pressure decrease in the crankcase over a certain period of time.

  • Page 11: Nameplate Information

    Nameplate Information All important information for identification of the compressor is printed on the nameplate located below the compressor oil pump. The type of refrigerant used should be stamped on the nameplate by the installer. Figure 3 The date of production indicates the year and week of production. The year and month of production are also part of the serial number (Jan.

    Installation Guidelines WARNING High pressure! Injury to skin and eyes, possible! Be careful when opening connections on a pressurized item. Compressor Handling Delivery Please check whether the delivery is correct and complete. Any deficiency should be reported immediately in writing. •...
  • Page 13 Installation Location Ensure the compressors are installed on a solid level base. Mounting Parts To minimize vibration and start/stop impulses, flexible mounting should be used. For this purpose, one set of spring mounting parts for each of the Stream models is delivered with each 4M* and 6M* compressor. Due to differences in weight (cylinder/motor side), different springs have to be used on both sides.
  • Page 14 Pressure Safety Controls High-pressure Control A high-pressure control with a maximum cut-out setting of 28 bar(g) is required. The high-pressure cut-out should have a manual reset feature for the highest level of system protection. Low-Pressure Control The normal minimum cut-out setting is 0.1 bar(g) for R404A. The low-pressure cut-out should have a manual reset feature for the highest level of system protection.

    Screens CAUTION Screen blocking! Compressor breakdown! Use screens with at least 0.6 mm openings. The use of screens finer than 30 x 30 mesh (0.6 mm openings) anywhere in the system should be avoided with these compressors. Field experience has shown that finer mesh screens used to protect thermal expansion valves, capillary tubes or accumulators can become temporarily or permanently plugged with normal system debris and block the flow of either oil or refrigerant to the compressor.

  • Page 20: Start-Up Leak Checking, Evacuation And Charging

    Start-up Leak Checking, Evacuation, and Charging WARNING Diesel effect! Compressor destruction! The mixture of air and oil at high temperature can lead to an explosion. Avoid operating with air. Leak Test The suction shut-off valve and discharge shut-off valve on the compressor must remain closed during pressure testing to prevent air and moisture from entering the compressor.
  • Page 21 To avoid motor damage the compressor MUST NOT be started, nor may high-potential testing be carried out under vacuum. Minimum Run Time Emerson Climate Technologies recommends a maximum of 10 starts per hour. The most critical consideration is the minimum run time required to return oil to the compressor after start-up.

    POE to absorb sufficient moisture to make it unacceptable for use in a refrigeration system. Since POE holds moisture more readily than mineral oil it is more difficult to remove it through the use of vacuum. Compressors supplied by Emerson Climate Technologies contain oil with low moisture content, and it may rise during the system assembling process.
  • Page 23 Oil Additives Although Emerson Climate Technologies cannot comment on any specific product, from our own testing and past experience, we do not recommend the use of any additives to reduce compressor bearing losses or for any other purpose. Furthermore, the long term chemical stability of any additive in the presence of refrigerant, low and high temperatures, and materials commonly found in refrigeration systems is complex and difficult to evaluate without rigorously controlled chemical laboratory testing.

    Compressors in the higher capacity range need some form of capacity control to accommodate varying refrigeration load. The capacity control kit supplied by Emerson Climate Technologies will reduce the refrigeration capacity along with a similar proportional reduction in power Input. This ensures optimum performance even in part load.
